摘要

Flowers of Sasa jotanii (Poaceae: Bambusoideae) from Isl. Miknrajima, Izu Islands, Japan, are observed on the basis of new flower characteristics and a new specific status of it is proposed here. Comparing the species with the most related allies, S.kurilensis and S. tsuboiana, S. jotanii is characterized by a large fusiform, incanus reddish-purple spikelet 25-36 (-40) mm long, 7-12 mm wide, extremely large elliptic non-dormant caryopsis (14.5-) 17-21.5 mm long in reproductive organs; its less decumbent culms, coriaceous and waxy foliage leaves, and lanceolate leaf blade without oral setae and sheath-margin fimbriae in sterile organs. Sasa jotanii is probably most closely related to S. kurilensis belonging to the section Macrochlamys.
